intermittent no start...what now.

[ptesmoke]

ok, you guys may remember my problems i was having before, chugging almost dying and sometimes dying. well here is what i replaced, and what i found... found ALOT of water in the gas (bad batch at the gas station apparently) which i assume buggered up most of my stuff. i replaced the fuel pump, fuel filter, pumped out the gas tank and put good gas in, plus some injector cleaner. replaced the plugs, plug wires, dist cap, dist pickup, ignition module, and everything ran great, except that if i let it sit for a little bit, it was hard to start, and, if i drove enough to warm it right up and let it sit for 5-20 mins, it wont start, itll turn over but just wont catch. at first i thought no fuel? or maybe a leaking injector because of the water?? right now im debating where i should focus my attention, should i pull the injectors and check to make sure theyre ok? i have 4 spares. also, could it be an intermittent fuel inertia switch?? what creeps me out is i had a big bottle of water on the passenger floor, picked it up and put it on the seat, and voila she fired up. but i cant replicate that everytime... so maybe it was just fluke. also , my heater core was leaking, so i bypassed it, but it soaked the passenger seat floor and carpet, is there anything there it could have shorted? the computer looks fine as it was up enough to be dry. im stumped, when she runs she runs great, but this no starting for like 30 mins is starting to piss me off. i dont think it could be another bad module. ill check for codes tomorrow but i doubt it would throw anything when it just wont start lol. thanks for any advice guys im going to go search and see what i can find out about that inertia switch and where it is. -ptesmoke

Bypass the inertia switch and remove it from being a possible issue. If it got soaked in coolant? That might be enough to bung things up.

Did she throw any codes?

When it's acting up? Check to see if you have spark. If you have good spark, and it won't fire up? I'd lean more towards a fuel issue.

Just some ideas. We are still fighting with ours LOL....

found ALOT of water in the gas (bad batch at the gas station apparently)
which i assume buggered up most of my stuff.

i replaced the fuel pump, fuel filter, pumped out the gas tank and put good gas in, plus some injector cleaner.

replaced the plugs, plug wires, dist cap, dist pickup, ignition module,

and everything ran great, except that if i let it sit for a little bit, it was hard to start, and, if i drove enough to warm it right up and let it sit for 5-20 mins, it wont start, itll turn over but just wont catch. at first i thought no fuel? or maybe a leaking injector because of the water??

right now im debating where i should focus my attention, should i pull the injectors and check to make sure theyre ok? i have 4 spares. also, could it be an intermittent fuel inertia switch?? what creeps me out is i had a big bottle of water on the passenger floor, picked it up and put it on the seat, and voila she fired up. but i cant replicate that everytime... so maybe it was just fluke. also , my heater core was leaking, so i bypassed it, but it soaked the passenger seat floor and carpet, is there anything there it could have shorted? the computer looks fine as it was up enough to be dry.

Have read where the ground near the EMC (engine computer) was bad and a few of the pin connections were iffy... if I remember right, the pins that were mostly suspect were #59 & #60. they noticed it more when someone rode in the passanger seat.

might want to check that out

[ptesmoke]

thank you for the reply!! i will check those pins out. it does seem to be getting somewhat better, since i put some lucas fuel conditioner in it. im suspecting a leaky injector....but.. god only knows.
